Atrial septal defect closure with the new Cardia Ultrasept II™ device with interposed Goretex patch: Mexican experience – has the perforation of Ivalon’s membrane been solved?

ObjectivesThe objective of this study was to demonstrate the safety and feasibility of using the new Cardia Ultrasept II™ device with interposed Goretex patch referring to the perforation of polyvinyl alcohol membrane.BackgroundGreat advances have been made in the development of devices for closure of atrial septal defect. The Cardia Ultrasept II™ with interposed Goretex patch is the modified last generation of Cardia devices, having the advantage of a super-low profile within the atria and an integral locking delivery-retrieval mechanism that ensures safe deployment. In addition, with the interposition of the Goretex, it has been possible to abolish perforation of Ivalon’s membrane as a complication.Methods and resultsPatients with ostium secundum atrial septal defect with surrounding rims with a minimum length of 5 mm and who underwent atrial septal defect closure with the new Ultrasept II™ with Goretex patch were included from two paediatric cardiac centres. Primary end point was to determine perforation of the Goretex membrane at follow-up; secondary end point included right ventricular diastolic diameter. In total, 30 patients underwent atrial septal defect closure at a median age of 6 (1–29) years. At follow-up for 6 (range, 1–15) months, freedom from perforations was 100%. A continuous decrease in right ventricular diastolic diameter was found with an initial median of 30 (25–49) mm and after catheterisation of 27.5 (18–33) mm, p=0.01, and Z-score of 2.6 (1.7–3.6) versus 1.9 (1–2.9) after procedure, p=0.01.ConclusionsThe new modified generation of the Ultrasept II™ device with interposed Goretex patch is a good alternative to achieve atrial septal defect closure safely and feasibly with no membrane perforation at follow-up.

Penanganan Perioperatif Pasien Dengan TOF dan Kardiomiopati Dilatatif Disertai Multiple Thrombus di Semua Ruang Jantung

Tetrallogy of Fallot (TOF) didefinisikan sebagai kondisi penyakit jantung kongenital yang ditandai dengan adanya obstruksi right ventricle outflow tract (RVOTO) baik stenosis pada supravalvar, valvar dan subvalvar, adanya ventricle septal defect (VSD), dextroposisi dari aorta dan hipertrofi ventrikel kanan. Kondisi ini diperberat dengan kardiomiopati dilatatif yang menyebabkan pasien jatuh pada keadaan gagal jantung dan pembentukan trombus multipel di semua ruang jantung. Tantangan perioperatif adalah terjadinya tet spell pada periode pre CardioPulmonary By pass (CPB), dan depresi kontraktilitas dapat menyebabkan gagal jantung. Pasca operasi beresiko tinggi untuk terjadi low cardiac output syndrome. Anak usia 2 tahun 10 bulan dengan diagnosis TOF dan kardiomiopati dilatatif disertai pembentukan trombus multipel yang menjalani prosedur total koreksi, dengan penyulit penyerta gagal jantung yang membaik dengan terapi medikamentosa, fungsi ventrikel kiri dan ventrikel kanan yang turun. Pasien dipasang monitoring standar EKG, SpO2, dan NIBP, kemudian dilakukan induksi inhalasi dengan sevofluran, selanjutnya dilakukan pemasangan invasif blood pressure pada arteri radialis kiri dan pemasangan kateter vena sentral (CVC) pada vena jugularis kanan. Dilakukan tindakan evakuasi trombus, penutupan VSD dengan goretex patch dan reseksi infundibulum kemudian dilakukan pericardial patch untuk melebarkan Right Ventricel Outflow Tract (RVOT). Pasca operasi pasien mengalami low cardiac ouput syndrome,dirawat selama 21 hari di ICU, dan dilakukan trakeostomi pada perawatan hari ke-9. Pasien berhasil disapih dari ventilator pada perawatan hari ke-13 dan pindah dari ICU ke ruang perawatan pada hari ke-21. Prosedur total koreksi pada pasien TOF dengan disertai kardiomiopati dilatatif merupakan tantangan tersendiri bagi dokter ahli anestesi. Persiapan pre-operasi yang baik, manajemen durante operasi dan monitoring yang seksama serta perawatan pasca operasi yang berkesinambungan menghasilkan hasil yang baik.

Creation of an intraatrial tunnel to produce a total cavo-pulmonary connection in a patient with dominant right ventricle, totally anomalous pulmonary venous connection, and pulmonary atresia with non-confluent pulmonary arteries

The surgical strategy for patients having a functionally single ventricle associated with totally anomalous pulmonary venous connection and pulmonary atresia with non-confluent pulmonary artery has yet to be agreed. We created an intraatrial tunnel to produce a total cavo-pulmonary connection in such a patient, also creating a confluence for the pulmonary arteries. By minimizing the use of the GoreTex patch, the patient was able to discontinue the use of warfarin.
